ok, so a fresh pool has just been installed and i needed to get the alkalinity right before adjusting the PH, so i added the desired amount of baking soda, this obviously raises ph too and did so to a very high level - off the scale. a couple of hours later i added dry acid to lower the PH, but within minutes off adding this the water started to change color to a brown/yellow type.
I know not to add huge amounts of acid at a time so its not that, any ideas?
Thanks
